Abstract: Abstract of the Disclosure One or a number of subsoil cavitie are employed for the storage or recovery of hot liquids.  At the time of heat storage,a heat-transporting liquid is extracted at low temperature at the lower end of each cavity, heated by heat exchange with an external fluid and reinjected at the upper end.  At the time of heat recovery, the heat-transporting liquid is extracted at high temperature at the upper end of each cavity, cooled by heat exchange with an external fluid and reinjected at the lower end.  The system comprises flow-arresting means for maintaining a minimum operating pressure at the top of each cavity, air or gas purge means, an expansion reservoir and a safety unit for ensuring one-way flow of the heat-transporting liquid from the expansion reservoir to each cavity.

Abstract: TITLE OF THE INVENTION            PROCESS FOR ELECTROLYTIC DIMERIZATION OF               N-SUBSTITUTED PYRIDINIUM SALT    ABSTRACT OF THE DISCLOSURE      A novel process for the preparation of an N,N'-di-substituted tetrahydro-4,4'-bipyridyl by electrolytic dimerization of the corresponding N-substituted pyridinium salt, characterized in that, using a system including an electrolytic cell having at least one diaphragm and an extractor disposed outside the electrolytic cell, the electro-lytic dimerization is carried out while an aqueous catholyte containing the corresponding N-substituted pyridinium salt is circulated between the electrolytic cell and the extractor in which the product is extracted into an extraction solvent, followed by separation of the aqueous phase which alone is recycled into the electrolytic cell.  According to the pro-cess of the present invention, the electrolytic dimerization can be continued stably for a long time, a high current efficiency can be attained and the desired product can be obtained in high yield.

Abstract: AN INTEGRATED CLOCK DRIVE CIRCUIT by Jay A. Thomas and Victor J. Stalick, Jr.                     ABSTRACT OF THE DISCLOSURE      A buffer amplifier, which prevents loading of the input signal, accepts at its input an amplified and equalized pseudo-ternary signal.  The output of the buffer amplifier is a-c coupled to the input of a precision differential amplifier, from which two output signals are obtained. One said output signal is representative of the positive pulses and the other said output signal is representative of the negative pulses of the pseudo-ternary signal. These two output signals are both applied to the inputs of a peak detector and a slicer.  The d-c output of the peak detector is also applied as one input to the slicer. Separate outputs are obtained from the slicer, one each for the positive and negative pulse inputs, and these two outputs are summed, and the summed output is then amplified to provide a clock-driver output.

Abstract: PROTECTIVE RELAYING SYSTEM     ABSTRACT OF THE DISCLOSURE    In a protective system which operates in response to a plurality of state quantities, for example voltage and current, one of which being a digital code signal having a long code length and transmitted over a trans-mission circuit, the density of the code errors of the digital code signal is detected.  A plurality of state quantities are processed by a processor including first means responsive to the digital code signal and second means not responsive to the digital code signal.  Either one of the first and second means is selected according to the density of the code errors.    According to this invention it is possible to operate the relaying system at high speed and high accuracy without being affected by code errors produced during the transmission thereof and without the necessity of using any locking means.  By using the detected code errors the relay can operate either a differential relay or a distance relay.

Abstract: TITLE          DENTAL PULP TESTER          ABSTRACT OF THE DISCLOSURE         A system for testing the dental pulp of a tooth by electrically stimulating the pulp with a pulsating signal hav-ing a continuously increasing amplitude.  The system includes a probe having an electrode adapted to contact the tooth, and a contact detection device for sensing when the probe elec-trode makes contact with the tooth.  At initial probe contact the contact detection device causes the amplitude of the stim-ulus to start increasing from an initial value.  The intensity continues to increase as long as the probe electrode is in contact with the tooth.  The electrical stimulus may be gen-erated by a voltage controlled pulse generator driving the primary of a transformer, with the secondary of the trans-former connected between the electrode probe and another elec-trode in electrical contact with the patient.  The transformer has a relatively low cutoff frequency so that the amplitude of the signal across the secondary is proportional to the pulse width of the incoming signal.  Consequently, as the control voltage to the voltage control pulse generator increases, the amplitude of the pulses across the secondary also increases.          The voltage control pulse generator also drives a counter, and the output of the counter is indicated on a digital display.          Since the amplitude of the control voltage is a function of the number of pulses generated by the pulse generator, the output of the counter indicates the amplitude of the electri-cal stimulus.  Alternatively, a ramp generator having its out-put connected to one end of the primary periodically grounded responsive to fixed frequency, fixed duration pulses from the output of an oscillator.  Consequently, the amplitude of the pulses across the secondary of the transformer increases with time.

Abstract: ABSTRACT       An apparatus is disclosed for indicating the presence of one or more predetermined substances in a fluid.  The fluid is passed through a duct (1) and the one or more predetermined substances reacts with one or more reagents to form  a reacted zone having a colour different from the unreacted zone.  An optical detection device (4,5) follows the boundary (2) of the zone (3) and its movement is controlled by control means (13). The velocity of the boundary (2) depends on the concentration of the substance(s)  in the fluid. Indication means (19) receives a signal from the control means (13), which relates to the velocity of the boundary (2).  If this velocity and hence the concentration exceeds a predetermined value, an alarm (18) is actuated.  The apparatus may include a reference optical detection device (6,7) with provision in the form of a comparison unit (11) to effect comparison between the two optical detection devices (4,5 and 6,7).  The apparatus can afford an accurate, countinuous indication of the presence of the predetermined substances.
